#merge!(other) ⇒ Object

Merge the given message with this message. A number of heuristics are applied in order to ensure that the result makes sense. For example, If the current message is not recursive but is being merged with a message that was recursive, this bit is maintained. If either message is authoritive, then the result is also authoritive.

Modifies the current message in place.
